Patented Feb. 25, 1908. 1

Application filed May 14. 1907. $eria1N0. 373.626.

T 0 all whom it may concern:

Be it known that I, GILBERT THoMAs WIL- SON, a subject of His Majestythe King of Great Britain and Ireland, residing at 71 Lambton Quay,Wvellington, in the Provincial District of Wellington, in the Colony ofNew Zealand, have invented. certain new and useful Improvements inRailway Fish- Plates, of which the following is a specification.

The invention relates to means employed for joining the ends of railwayrails, girders, beams and the like. According hereto two jaws areemployed respectively shaped to fit upon opposite sides of the ends tobe joined. One jaw has projecting lugs which respectively pass intoholes formed in each of said ends and a bolt passes through one aw andthrough a hole formed by corresponding recesses in the ends and screwsinto a threaded hole in the opposing jaw.

For purposes of illustration the invention is shown in the drawing asapplied to the joining of two railway rails and in said drawingFigure lis a transverse sectional elevation, Fig. 2 an end perspectiveelevation, Fig. 3 a similar view to Fig. 2 with the jaws removed, andFig. 4 a plan of the jaws. Fig. 3 shows two rails 1 and 2 respectivelywhich are to be connected. Rail 1 has the hole 3 through the web and asemicircular recess 4 in its end. The rail 2 has the hole 5 in the weband the semi-circular recess 6 in its end.

Referring now to Figs. 1, 2 and 4 the jaw 7 has the stifiening ribs 8and upon its inner face which is shaped to fit between the head and theflange of the tail, are the lugs 9 and 10 which pass freely into theholes 3 and 5 in the respective rails. The jaw 11 is shaped upon theside opposite to jaw 7 and a bolt 12 passing through a hole in the jaw7, through the hole formed by the corresponding semicircular recesses 4and 6 in the rail ends, screws through a threaded hole in the jaw 11 andhas a nut 14 upon its end. A thin metal liner 15 extending the length ofthe jaw may be inserted between the top of the jaw 11 and the rail headas shown in Fig. 1 but this may usually be dispensed with.

What I do claim and desire to secure by Letters Patent of the UnitedStates is:

1. A jointing device comprising in combination a jaw having a pair ofprojecting lugs adapted to take into holes in the respective parts to bejoined, a second jaw having a screw threaded hole, a bolt passingthrough a hole in the first jaw and screwing into the threaded hole inthe second aw substantially as specified herein.

2. In jointing devices in combination with two parts to be joined, a jawhaving projecting lugs thereon respectively passing into holes formed ineach of said parts, a bolt adapted to pass through a hole in said jaw,the parts to be joined having corresponding semi-circular recesses intheir ends which together form a hole for the passage of the bolt, and asecond jaw having a screw threaded hole through which the bolt isscrewed substantially as specified.

In testimony whereof I have signed my name to this specification in thepresence of two witnesses.
